The fsck command for sfs filesystems is a modified version of the fsck command for ufs filesystems. From the administrator's point of view, the two commands are virtually identical. Both have the same number of passes, and all error messages printed by the ufs version of fsck are also produced by the sfs command. The changes to fsck are in these major areas:
As mentioned in ``The sfs filesystem type'', two inodes are allocated for each file on an sfs filesystem. The even-numbered inodes contain standard filesystem information and are basically identical to ufs inodes. The odd-numbered inodes, or alternate inodes, contain security information. These modifications ensure that only even-numbered inodes are checked for filesystem consistency.
